Hama Bead Molecules Pt.3 - Ghrelin

Ghrelin is a hormone produced by enteroendocrine cells of the gastrointestinal tract, especially the stomach, and is often called a "hunger hormone" because it increases food intake.

Hama Bead Molecules Pt.2 - Leptin

Leptin is a hormone predominantly made by adipose cells and enterocytes in the small intestine that helps to regulate energy balance by inhibiting hunger.

Protein Motifs pt.2 - beta-alpha-beta motif

A beta-alpha-beta motif is composed of two beta strands joined by an alpha helix through connecting loops. The beta strands are parallel, and the helix is also almost parallel to the strands.

Protein Motifs pt.1  - alpha-alpha hairpin

A helix hairpin, also known as an alpha-alpha hairpin, is composed of two antiparallel alpha helices connected by a loop of two or more residues.

Protein Motifs pt.4 - four helical bundle

A four helix bundle is composed of two helix hairpins.

Protein Motifs pt.3 - beta-beta hairpin and beta meander

A beta hairpin is a common supersecondary motif composed of two anti-parallel beta strands connected by a loop. A beta-meander consists of consecutive antiparallel-beta strands linked by hairpins.
