A taxis (from Ancient Greek τάξις (táxis) 'arrangement, order'; [1] pl.: taxes / ˈ t æ k s iː z /) [2] [3] [4] is the movement of an organism in response to a stimulus such as light or the presence of food. Taxes are innate behavioural responses.
The lipid globules contain a complex mixture of carotenoid pigments, which provide the screening function and the orange-red colour, [40] as well as proteins that stabilize the globules. [41] The stigma is located laterally, in a fixed plane relative to the cilia, but not directly adjacent to the basal bodies.
The structure forms an internal hydrophobic cavity in which 1-2 lipids can be bound. The outer surface of the protein is hydrophilic, allowing the complex to be soluble. The use of hydrophobic interactions, with very few charged interactions, allows the protein to have broad specificity for a range of lipids. [9]
Protein–lipid interaction is the influence of membrane proteins on the lipid physical state or vice versa.. The questions which are relevant to understanding of the structure and function of the membrane are: 1) Do intrinsic membrane proteins bind tightly to lipids (see annular lipid shell), and what is the nature of the layer of lipids adjacent to the protein?
Common lipid signaling molecules: lysophosphatidic acid (LPA) sphingosine-1-phosphate (S1P) platelet activating factor (PAF) anandamide or arachidonoyl ethanolamine (AEA). Lipid signaling, broadly defined, refers to any biological cell signaling event involving a lipid messenger that binds a protein target, such as a receptor, kinase or phosphatase, which in turn mediate the effects of these ...
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
"Fixed action pattern" is an ethological term describing an instinctive behavioral sequence that is highly stereotyped and species-characteristic. [1] Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser.
Proteins that have been myristoylated are involved in signal transduction cascade, protein-protein interactions and in mechanisms that regulate protein targeting and function. [13] An example in which the myristoylation of a protein is important is in apoptosis, programmed cell death. After the protein BH3 interacting-domain death agonist (Bid ...
