helix A three-dimensional spiral curve. In mathematical terms, a helix can be described as a curve turning about an axis on the surface of a cylinder or cone while rising at a constant upward angle from a base. 2. Something, such as a strand of DNA, having a spiral shape.

Helix  (gastropod) Helix is the type genus of the family Helicidae. The best-known species include Helix aspersa, the common, or brown garden snail, and Helix pomatia, the Roman snail, Burgundy snail, or edible snail. H. pomatia and some other species are eaten as escargots.

How to Care for a Helix or Forward Helix Piercing This article discusses helix and forward helix ear piercings. A helix piercing is most commonly called the top ear piercing or the ear cartilage, and the forward helix is the small piece of skin at the very front of the helix that attaches the ear and the temple together.

Cartilage piercing Helix: The outer rim of cartilage on the ear, extending from just above the lobe to its apex and then curving down slightly to meet the head.[1] Forward Helix: The area of the helix closest to the head; generally any piercing between the apex of the helix and where the helix joins the head.

Helix piercing Helix piercing. The helix piercing is a perforation of the helix or upper ear (cartilage) for the purpose of inserting and wearing a piece of jewelry. The piercing itself is usually made with a small gauge hollow piercing needle, and typical jewelry would be a small diameter captive bead ring, or a stud.

Alpha helix Similar structures include the 310 helix (hydrogen bonding) and the π-helix (hydrogen bonding). The α helix can be described as a 3.6 13 helix, since the i + 4 spacing adds 3 more atoms to the H-bonded loop compared to the tighter 3 10 helix, and on average, 3.6 amino acids are involved in one ring of α helix.

- The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder. An important property of DNA is that it can replicate, or make copies of itself.NA is a double helix formed by base pairs attached to a sugar-phosphate backbone. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms.

- The a-helix. 3.2 Secondary structure (continued) We can describe the arrangement of atoms around the peptide link (the conformation) by giving the degree and direction in which the Ca-CO and N-Ca bonds are rotated. When a number of successive peptide links have identical rotations the polypeptide chain takes up a particular secondary structure. There are several types of secondary structure, but we will concentrate on just two: the a-helix and the b-pleated sheet. In both cases you will see how the regular conformation allows the structure to be stabilised by forming many relatively strong hydrogen bonds. The a-helix The a-helix is like a narrow-bore tube.

double helix Medical Definition of double helix. : a helix or spiral consisting of two strands in the surface of a cylinder that coil around its axis; especially : the structural arrangement of DNA in space that consists of paired polynucleotide strands stabilized by cross-links between purine and pyrimidine bases—compare alpha-helix, watson-crick model.

What is DNA? Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.An important property of DNA is that it can replicate, or make copies of itself.he structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.

- The secondary structure of insulin is an example of the alpha helix (there are three segments). The intramolecular hydrogen bonding in the alpha-helix is between the amide groups. The hydrogen on the amide of one protein chain is hydrogen bonded to the amide oxygen of the neighboring protein chain.

Helix Piercing Types of Helix piercing. Single helix piercing: This refers to the single perforation made in the upper cartilage or helix region. Double helix piercing: Here double perforations are made in the upper cartilage of the ear. Triple helix piercing: In this kind, three piercings are done one after the other.

Definitions &Translations A helix (pl: helixes or helices) is a type of smooth space curve, i.e. a curve in three-dimensional space. It has the property that the tangent line at any point makes a constant angle with a fixed line called the axis. Examples of helices are coil springs and the handrails of spiral staircases.

Alpha helix The alpha helix (α-helix) is a common secondary structure of proteins and is a righthand-coiled or spiral conformation (helix) in which every backbone N-H group donates a hydrogen bond to the backbone C=O group of the amino acid four residues earlier (hydrogen bonding).ifferent amino-acid sequences have different propensities for forming α-helical structure. Methionine, alanine, leucine uncharged, glutamate, and lysine (MALEK in the amino-acid 1-letter codes) all have especially high helix-forming propensities, whereas proline and glycine have poor helix-forming propensities.
