Peptide in a sentence

Peptide bond A peptide bond (amide bond) is a covalent chemical bond linking two consecutive amino acid monomers along a peptide or protein chain. citation Pauling L. (1960) The Nature of the Chemical Bond, 3rd.

They catalyse the hydrolysis of interior peptide bonds in peptide chains, as opposed to exopeptidases (another class of enzymes, that catalyse the hydrolysis of terminal peptide bonds, liberating one free amino acid at a time).

This extends the fundamental process identified by Francis Crick (one gene-one peptide) in which the sequence is: DNA → RNA → peptide (proteins are made of one or more polypeptide chain; e.g. haemoglobin is a four-chain peptide).

We recommend Ole Henriksen Pout Preserve Peptide Lip Treatment ($29), a peptide-rich balm that helps to boost collagen and to smooth and hydrate parched lips.

However, the peptide's toxicity to the host also increases in line with the peptide's positive charge—it damages the host organism's cells as it kills bacteria.

A candidate nucleic acid is peptide nucleic acid ( PNA ), which uses simple peptide bonds to link nucleobases. citation PNA is more stable than RNA, but its ability to be generated under prebiological conditions has yet to be demonstrated experimentally.

However, not all peptide groups have the same effect on folding; nonnative isomers of other peptide groups may not affect folding at all.

If we deal with a non-peptide organic libraries library it is not as simple to determine of the identity of the content of a bead as in the case of a peptide one.

Peptide lyases A seventh catalytic type of proteolytic enzymes, asparagine peptide lyase, was described in 2011.

Proteases can either break specific peptide bonds (limited proteolysis), depending on the amino acid sequence of a protein, or break down a complete peptide to amino acids (unlimited proteolysis).

The peptide chain can be cross-linked to the peptide chain of another strand forming the 3D mesh-like layer.

The signal sequence on the N-terminal of the peptide is recognized by a signal recognition particle on the endoplasmic reticulum, which will be responsible for directing the pre-pro-peptide into the endoplasmic reticulum.

Blood samples were taken from the participants at the beginning and after four weeks of breathing exercises to check the amyloid beta peptide levels in their blood.

Does that mean you have to wait for the crow’s feet and laughter lines to show up before you start using peptide skincare?

In addition, research shows that ARA 290 peptide protects against typical inflammatory reactions and enhances tissue protection.

The drugs work by suppressing appetite by mimicking the hormone glucagon-like peptide-1 (GLP-1), which is released after eating, making people feel so they eat less and lose weight.

The drug works as an appetite suppressant by mimicking a hormone called Glucagon-like peptide-1 (GLP-1).

The Rhode Peptide Lip Treatment in shade ‘toast’ is a must in anyone’s handbag subtle touch of that goes a long way.

These drugs belong to a class of medications called glucagon-like peptide-1 (GLP-1) receptor agonists, which mimic the action of a naturally occurring hormone in the body that regulates blood sugar levels and appetite.

We need less washing and filtration steps compared to classic peptide synthesis.
