Sperm olfactory receptors


Volume, pH, sperm concentration, motility, and normal morphology were determined according to World Health Organization guidelines for semen analysis, after liquefaction at room temperature. In this context, the identification of seminal OR repertoire is an interesting field in the research of reproduction. Our results open new insights into OR involvement in sperm maturation and migration. The ion flow changes the electrical potential of the cell and starts the electrical signal that will make it all the way to the brain—that is if the receptor is in your nose. An increasing importance has been suggested for spermatozoal RNA Ostermeier et al. Furthermore, we observed a distinct expression pattern for each OR protein and investigated effects of the respective OR ligands. Class I receptors resemble the family initially found in aquatic animals, thus it was suggested that these receptors may be specialized in detecting the water-soluble odorants [ 2 - 4 ].

It comes in two forms: Depolarisation The process of reducing the electrical potential of a cell or membrane, an essential part of the transmission of electrical impulses. New ones are still being discovered. Phenylketonuria Also known as PKU, this is a genetic disorder in which the enzyme responsible for metabolising the essential amino acid phenylalanine into tyrosine is inactive. Amygdala A small, almond-shaped structure within the brain involved in emotions, particularly fear.

Sperm olfactory receptors



Description: Actin One of the main proteins involved in muscle contraction. Ion channel A protein or assembly of several proteins in the cell membrane that opens and closes to let ions move in and out of cells. Primary structure The amino acids that make up a protein or polypeptide chain, linked by peptide bonds. Light-dependent reactions The first stage of photosynthesis. There are two main types:

First, I love your channel. It is a tremendous resource for which I am personally grateful. Question: can you suggest materials or resources for someone who identifies as gender-queer? A friend of mine says they feel marginalized by both binary identifying peoples AND trans peoples because of the ambiguity of their identification. I don't think they should feel marginalized or ostracized, but I don't know with whom or what they can commune and find acceptance and understanding. Suggestions?
